did you take your battery to get tested yet? i didn't mention in my last post w/you but go to any auto store and have them run a test on the battery. it's old, probably failing and causing voltage drops which then is causing your misfire. it wouldn't hurt to also grab a new set of plugs too but start with the battery (and even swap around coils as others said too if issues persist.)

I just got a chance to work on my car. I replaced the coil, spark plug and wire. Code p0305 went away and the check engine light is off. But now when I plug in my tester it says I have code p0300. I did notice that the battery is the original one. But its still putting out 800 cca. Do you think I should change that?

My battery finally died yesterday also. Was the original also. Had a 2014 date on it. 8500 miles on car.
Pretty good for an AC/Delco. Think im going with the Duralast Platnium AGM. My local Autozone has the correct replacement.

I went to the Chevy dealer and got the same battery. Surprisingly they are not AGM.

Thanks to all for your responses.

I get it.

Good to know the battery was the culprit.
